My 'invention relatesl to 'improvements In i A water heaters and-more particularly to the type used i'nconjunction with cooking stoves and ranges, and has ttor its object to provide a water-heater by meansef which waiter may be heated either by the combustion of fuel in the usual iifre boXorby a-gas .name or othersource vof' heat independentithe'reo. A further object 4of the invention is to :provide a water heater in whichv diEerent portions of the heater may-be used independently of each other for heating water 'altdifferentv times.v A still 'further object of the invention is to .provide aA water heater so constructed lthat expansion vand 4contraction of the parts will notbe detrimental tothe heater. To these and other ends the inten-l tion consists in certain improvements and combinations of parts, all as will ice-hereinafterV more fully Vdescribed,-the novel features being pointed out inthe claimsfaft the end ofthe specification. v

Referring to the -fdrawings' by .numerals 1.0

' representen `-stove'or range of any preferred type provided with =a {ire-'box 1l having the usual grate lbars Above ythe tire-box 111 is aheatingehamber 13 rrein'whebaleads-a l passage way 14 for carri ning .eifxerneke and, other products of combustion.- -One of the walls of the tire-box 11 is formed by a plu-y rality' @ingreep 4er spaced i-superimpesed coils 15, between which are positioned iillers.. Y

16 .for 4closing the ep'enngs'between the coils to preventthe escape of 'the fuel `from the. 'l

iireeb '0X Y as 'well as to prevent: 'air entering therein vexcept through tbegrateat the bettem thereof; v The coils 1-5 are' preferably formed oit' one piece, the ends of which are" f' suitably connected with lthechanibe'rs 17 and of a stove or'-` 418 offa head formed by the plates 19 and 20 rigidly connected as shown in Fig. 5. The plate 20 is provided with a circumferential flange 21v which serves to space said plate from the plate 19. Between the flange 21 and plate 19 is positioned a 4packing ring 22 adaptedy to form a water tight joint between said members. The plate 20 is also provided with a centrally positioned transverse member 23 fordividing the head into the sepayrate chambers 17 and 18. VBetween the member 23 and the plate 19 is positionedva packing strip 24: adapted toform a water tight I joint between the chambers. If it is desired to make the head more rigid the same mav be cast in one piece withl the dividing wall 23 integral therewith without departing from the spirit of the invention'. A water supply pipe 25 connects with the chamber'lS- through the plate 20. The supply pipe may.

be connected with any suitable source for supplying' Water to the'chambei'. A discharge pipe 26 leads from the chamber 17 to a tank or other container (not shown) pro vided for storing vhot Water adapted to be circulated through the coils 15 when fuel is burned in the lire-box 11. rlhe head formed by the plates 19 and 20 is preferably positioned at the back of the stove in a combustion chamber 27 positioned adjacent the fire-box 11 as shown in 2. A series or group of coil pipes 28, preferably'smaller in diameter and of a greater numberthan -the coils 15, have their lower ends communieating With the chamber 18 and their upper ends with the chamber 117 so that Water entering the lower chamber will circulate through the coils into theupper chamber and out through the discharge pipe 26 lat the same time that VWater is circulating through the coils When fuel is being burned in both of the combustion chambers. Beneath the coils 28 is positioned anyvsuity able type of gas burner 29, provided With a mixer 30 adapted to receive gas from a supply pipe Sl'through a valve 32 for control' ling the supplyV of gas to the burnen A hingeddoor 33 is provided to adord access to thek chamber 27 and burner 29. Suitable openings 34 and .35 are shown leading` to the "o chamber 27 for furnishing a suiiicient sup- ,ply of air to the burner 29. A damper 36 is positioned at the top of the chamber 27 for discharging therefrom into the chamber 13,

the chamber. vBy attachingthe `groups of coils 15 and 28 to a single rigid-head free'to move" as shown, l overcome the usual trouble experienced in the uneven eXpansionand M contraction of Water tube kheatersy of the spaced or fixed head type. In. the present instance the head and coils both are free to move in either direction when expanded and the products of combustion accumulating1 in contracted as the pipes and 26 which supvport said members are loosely positioned through the back Wall of the stove. lt Will be understood that the two sets of tubes l5 and 28 form independent Water circulating mediums which may be heated separately or V'at the same time by the burning of 11nrelated supplies of fuel from separate and independent sources.

I claim as my invention:

1. ln a Water heater, the combination With a fire-box, of a Water head, a Water circulatingg` medium connected rWith the head and arranged to be heated by the combustion of fuel in said lire-box, asecond Water circulatine medium connected with the head and a liquid` fuel burner arranged to supply heat to the second mentioned medium independ` circulating tube having one of its ends con-V nected With the lnletchamber and its other` end with the outlet chamber, said tube forming a Wall of the flre-boX,-a plurality of tubes each having one 'of its ends connected with said inlet chamber and its other end With said outlet chamber, and means independent of theiire-box for heating` the last mentioned tubes.
